Cytogenetics characterization of Crenuchus spilurus (Günther, 1863): a remarkable low diploid value within family Crenuchidae (Characiformes)
(2018-01-01)
Conventional and molecular cytogenetic analyses were performed in specimens of the Neotropical Crenuchus spilurus freshwater fish species from a single location (Caeté River, Brazil). All specimens presented diploid values ...
Friedelin in maytenus ilicifolia is produced by friedelin synthase isoforms
(2018-01-01)
Triterpenes are interesting compounds because they play an important role in cell homeostasis and a wide variety exhibiting defense functions is produced by plant secondary metabolism. Those same plant secondary metabolites ...
Wild birds and urban pigeons as reservoirs for diarrheagenic Escherichia coli with zoonotic potential
(2017-05-01)
In order to describe the role of wild birds and pigeons in the transmission of shiga toxigenic Escherichia coli (STEC) and enteropathogenic Escherichia coli (EPEC) to humans and other animals, samples were collected from ...
Detection of bluetongue virus in Brazilian cervids in São Paulo state
(2018-01-01)
Viral hemorrhagic diseases in cervids occur worldwide and include epizootic hemorrhagic disease (EHD), bluetongue (BT), and adenoviral hemorrhagic disease (AHD). Since gross lesions in all three hemorrhagic diseases are ...
Microbial Communities of the Gut and Nest of the Humus- and Litter-Feeding Termite Procornitermes araujoi (Syntermitinae)
(2018-01-01)
The evolution of the symbiotic association with microbes allowed termites to decompose ingested lignocellulose from plant-derived substrates, including herbivore dung and soil humus. Representatives of the Syntermitinae ...
High-throughput analysis of the satellitome revealed enormous diversity of satellite DNAs in the neo-Y chromosome of the cricket Eneoptera surinamensis
(2017-12-01)
Satellite DNAs (satDNAs) constitute large portion of eukaryote genomes, comprising non-protein-coding sequences tandemly repeated. They are mostly found in heterochromatic regions of chromosomes such as around centromere ...
Strategies of the control of an outbreak of leptospiral infection in dairy cattle in Northeastern Brazil
(2018-07-03)
The aim of the present study was to describe the strategies of the control of an outbreak of leptospiral infection in dairy cattle in Maranhão State, Northeastern Brazil. In the period from January to July 2015, 18 (17%) ...
Highlighting Astyanax species diversity through DNA barcoding
(2016-12-01)
DNA barcoding has been used extensively to solve taxonomic questions and identify new species. Neotropical fishes are found in a wide variety of shapes and sizes, with a large number of species yet to be described, many ...
Convergent Evolution of Slick Coat in Cattle through Truncation Mutations in the Prolactin Receptor
(Frontiers Media Sa, 2018-02-23)
Evolutionary adaptations are occasionally convergent solutions to the same problem. A mutation contributing to a heat tolerance adaptation in Senepol cattle, a New World breed of mostly European descent, results in the ...
Est16, a New Esterase Isolated from a Metagenomic Library of a Microbial Consortium Specializing in Diesel Oil Degradation
(Public Library Science, 2015-07-27)
Lipolytic enzymes have attracted attention from a global market because they show enormous biotechnological potential for applications such as detergent production, leather processing, cosmetics production, and use in ...
